  1. 1. Continuous Fibre Reinforced Oxide/Oxide Composites

    Författare :Magnus Holmquist; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polycrystalline oxide fibre; zirconia; single crystal oxide fibre; hot isostatic pressing; hot pressing; alumina; mullite; sapphire; tape casting; interface; VibroIntrusion; interphase; continuous fibre reinforced ceramic composite; mechanical properties; oxide fibre; ceramic matrix composite;

    Sammanfattning : The appealing properties of ceramics include retention of strength and hardness at high temperatures, chemical inertness and low density. However, monolithic ceramics fail in a brittle, unpredictable manner making them unsuitable for many applications where reliability is a key requirement. LÄS MER

  3. 2. Thin-fibre signalling in humans: Cortical processing of sensory afference and autonomic efference

    Författare :Karin Rylander; Göteborgs universitet; []
    Nyckelord :CT afferent; thin fibre; autonomic; insula; fMRI;

    Sammanfattning : Thin nerve fibres innervate the entire human body and mediate sensations such as pain, temperature and visceral sensory input. Moreover, a special class of unmyelinated afferents responsive to light touch has recently been found in humans: C-tactile (CT) fibres. LÄS MER

  4. 3. Multi-functional composite materials : CFRP thin film capacitors

    Författare :Tony Carlson; Patrik Fernberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : The use of lightweight materials in structural applications is ever increasing. Today, lightweight engineering materials are needed to realise greener, safer and more competitive products. LÄS MER

  5. 4. Steel fibre corrosion in cracks : durability of sprayed concrete

    Författare :Erik Nordström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Steel fibre reinforced sprayed concrete is common practice for permanent linings in underground construction. Today there is a demand on "expected technical service life" of 120 years. Thin steel fibres could be expected to discontinue carrying load fast with a decrease of fibre diameter caused by corrosion, especially in cracks. LÄS MER

  7. 5. Durability of sprayed concrete : steel fibre corrosion in cracks

    Författare :Erik Nordström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : A combination of sprayed concrete technique and steel fibre technology gives obvious advantages when saving the work needed to place conventional reinforcement. In rock strengthening applications this is most accentuated. Sprayed concrete in general, made by skilled workmen, will generally be of high quality and good durability. LÄS MER
